Meson gravitational D-form factors and symmetry breaking in low-energy QCD
Mamiya Kawaguchi, Kazuhiro Tanaka, Mitsuru Tanaka
We investigate meson gravitational D-form factors in the three-flavor linear sigma model and their connection to symmetry breaking in low-energy QCD. Within the scalar meson domina…
Proton mass decompositions in the NNLO QCD
Kazuhiro Tanaka
Proton matrix elements of the QCD energy-momentum tensor (EMT) are expressed by the gravitational form factors. The forward values of the gravitational form factors allow for a dec…
QCD sum rules for quark-gluon three-body components in the B meson
Tetsuo Nishikawa, Kazuhiro Tanaka
We discuss the QCD sum rule calculation of the heavy-quark effective theory parameters, and , which correspond to matrix elements representing quark-gluon three-body com…
Evolution equation for the B-meson distribution amplitude in the heavy-quark effective theory in coordinate space
Hiroyuki Kawamura, Kazuhiro Tanaka
The B-meson distribution amplitude (DA) is defined as the matrix element of a quark-antiquark bilocal light-cone operator in the heavy-quark effective theory, corresponding to a lo…
Operator product expansion for B-meson distribution amplitude and dimension-5 HQET operators
Hiroyuki Kawamura, Kazuhiro Tanaka
When the bilocal heavy-quark effective theory (HQET) operator for the B-meson distribution amplitude has a light-like distance t between the quark and antiquark fields, the scale \…
Q_T Resummation in Transversely Polarized Drell-Yan Process
H. Kawamura, J. Kodaira, H. Shimizu +1
We calculate QCD corrections to transversely polarized Drell-Yan process at a measured of the produced lepton pair in the dimensional regularization scheme. The distrib…
